Question

The Kirchhoff's first law ($\sum$i=0) and second law ($\sum$iR=$\sum$E) , where the symbols have their usual meanings, are respectively based on :

• A. Conservation of charge, conservation of momentum
• B. Conservation of energy, conservation of charge
• C. Conservation of momentum, conservation of charge
• D. Conservation of charge, conservation of energy

Answer 1

The correct option is D Conservation of charge, conservation of energy

Kirchhoffs first law says that no charge can be accumulated at a junction which implies conservation of charge Kirchhoffs second law states that the energy liberated in the circuit comes from the battery which implies the conservation of energy
